Cipher Text

What is Cipher text?

Ciphertext is data encrypted text. It is the encrypted result of the plaintext. Cipher is the method of encryption and ciphertext is the result.

Cryptography is the study and practice of thrashing data. In today’s time, cryptography is measured a stem of both arithmetic and computer science, and is associated intimately with information hypothesis, computer sanctuary, and manufacturing.

In cryptography, code has a certain meaning; it means the substitution of a unit of plaintext which means meaningful phrases or words with some coded words. Cryptography is of two types.

* Symmetric key cryptography

* Asymmetric key cryptography

Conversion of data into a form of ciphertext is known as Encryption. The ciphertext is not easily understood by common man. Thus is how the data can be protected by it being converted into secret code. To read an encrypted file the user needs to have a key to decode it into plaintext and read it.

There are two ways to encrypt a file

* Symmetric key encryption

* Asymmetric key encryption

Conversion of secret code into plaintext by use of key and algorithms is known as decryption. The ciphertext is not easily understood by common man. Thus it needs to be decoded and the process for doing the same is known as decryption. Decryption is the reverse process of Encryption.

There are two ways to decrypt a file

* Symmetric key Decryption

* Asymmetric key Decryption
